Strengths:    Lightweight, performs well wide open (for XC) and lockout works well. Rebound adjust works well and has fine adjustment. Easy to disassemble and replace/oil seals.

Weaknesses:    "Gate" position is OK... leaves a bit to be desired as as it feels like it clunks in the initial stages of travel in this setting. Does, however, firm up the shock. Burns through upper eyelet bushings (<6 months but I ride quite a bit)

Bottom Line:   
Shock came with the bike and I've been pretty happy with it. Would recommend it to a friend if you can find it for a good price.

Strengths:    Motion control with adjustable floodgate - takes out all the pedal bob from my single pivot suspension yet absorbs big hits perfectly. I am a huge fan of Motion Control

Plush, linear spring with big air chamber

3 position switch from lockout, floodgate to fully open is very convenient

Rebounding damping works well, lots of adjustment clicks

Weaknesses:    Damper is not serviceable in the MC series - you can replace the air can seals yourself cheaply, but if the damper breaks (oil leaks, clunking, anything of that sort) you have to chuck the whole assembly and get a bike shop to get new parts from SRAM to install it - it's expensive and I resent having to pay a large portion of the full price of the shock just to keep it working after a mere 30 hours of riding. The Monarch line is supposed to be much more serviceable, even the damper.

Bottom Line:   
For 6 months of riding, I was in love with the shock. The pedal platform is great at killing pedal bob while damping moderate and big hits and can be disabled completely for a fully active very plush feel when needed. The adjustments are simple, intuitive and require no tools. Motion Control+Floodgate = Win. Of course, the adjustable air spring rate means you get the exact feel you want, and the large air chamber makes it feel very smooth and linear. I rode this shock down stairs and a few mild jumps, though it may not be designed for this. Anyway, it's great for XC and AM, but perhaps not rugged enough for anything more.

After those 6 months, about 30 hours in total, the damper gave up the ghost. It might be because the shock mounting rod was not centered in the eyelet when the shop installed it, so the shock compressed at an angle and this put stress on it - who knows.

I give 3 chilis for value because for the sticker price of this shock, it needs to be more reliable and rugged. Overall, it deserves 5 chilis because it feels great.

Strengths:    Lots of adjustments - once you get it dialed in it works great.

Weaknesses:    I put in 150 pounds at night, 8 hours later its down to 100 pounds.

Bottom Line:   
I am sure its a great shock if it would hold air - this one is going to be returned to SRAM for replacement.

Date Reviewed: November 16, 2007

Strengths:    Easy setup, very plush. Motion control gate and open positions are used often. Lockout is seldom used as my bike does not bob much, but on really steep and smooth climbs it is nice as it prevents the rear end from sagging from weight transfer.

Weaknesses:    Hardware is way too spendy.

Bottom Line:   
Great shock for a reasonable price. My Monk's rear suspension has a very linear 3 to 1 ratio, so I would expect similar results with other designs with similar action.

Strengths:    The best part is the option that you have. I can go from a super plus shock for the trail or a firm when i have to go on the road. Its also very light.

Weaknesses:    So far i have not find any and I do not think I will.

Bottom Line:   
If you wan t a reliable and durable shock the Rockshox MC 3.3 is the one.

Strengths:    Light weight, easily adjustable, holds air, great lockout for road sections, easy to service, large air can=low pressure

Weaknesses:    none so far

Bottom Line:   
So far i am pleased with this product. It does its job, you can ride in fully open (for the really bumpy stuff and techy climbs), Motion control (pro Pedal) for the smooth singletrack and fully locked-out which i love since i do a lot of road sections to the trailhead.

The shock is plush and quiet and holds its air pressure.
And in comparison with the fox shocks, the MC 3.3 requires about half or the air pressure (i am 155 lbs and for 20% sag i have the shock set at about 70 psi).

Strengths:    Lightweight, motion control dampening works perfectly and is easily fine-tunable, rebound is very adjustable and shock performs well over small and large bumps, never bottoms out

Weaknesses:    hardware is expensive

Bottom Line:   
***This review is for the Rock Shox MC 3.1*** I was skeptical when buying this shock from reading previous posts regarding the MC line of Rock Shox but thus far I have been nothing short of impressed. This shoc was OEM equipment off of a Trek Fuel and it works perfectly with my Azonic's Horst link suspension system. The savings in weight over my Romic is considerble and while certainly not as plush as the Romic coil, the overall performance has been superb. After installation, I gave it no time to break in and rode 41 hours in three days along the Colorado trail covering 202 miles of singletrack and didn't lose one pound of pressure. I've now got a little over three months into this shock and ride three - four times per week on the Colorado front range and this shock has thus far exceeded my expectations.

Strengths:    adj range
reliability (yes really)
very large air volume

Weaknesses:    i cant really think of any. it takes a little time to setup when you are use to all of these "fancy" shock out there

Bottom Line:   
i really really like this shock. all the major adj are right at your finger tips. the motion control also effects the over all compression of the shock. the one guy said that the clicks in the rebound do little to the shock and that is right to an extent each click is a very small adj but there are 30 clicks i think and the total range it very wide. this shock is actually very light, much lighter than expected and i was kinda worried until my last couple of rides, which where are dh parks with lifts and the shock has performed much better than expected in those very harsh situations. i shock has about 30-40 dh miles under it now and never once even hickuped.

the ride

it is a little on the harsh side but less then most any other platform shock on the market (yes even pro pedal). it take big hits very well. it also is more active than you might think but it will only show it when you push it hard, it lets you know how well it can work but you finding it easy to find traction in some difficult situations.

the setup

this shock requires some really low air pressures. i weight 250 lbs+ with gear and i only have to run 130 psi in the shock and i have not bottemed it once let (gotten close though) also i'm running about 50% rebound and about 25% motion control. i bet the reason people are having to many problems it because the shock was not installed right or setup right.

the end comment

don't let these other review worry you too much. i have pushed this shock very hard and its loving all of it (so am i). it can take whatever you want to throw at it.

Strengths:    Motion Control works great. Love the on the fly adjustability.

Weaknesses:    Rebound adjustment not too responsive.

Bottom Line:   
When I first purchased the bike the shock lost all air pressure after 1 day. Brought it back and the shop rebuilt it for me at no charge. Then after about a year of regular use, I had the same exact problem Ben had. What actually happened was the internal rebound chamber just unscrewed from itself and released all the oil. So I brought it back again and the shop had a replacement for me installed in just 2 days for no charge. Shop is great, shock ain't so great.

Bottom Line:   
Can´t complain about this rear shock! Didn´t have to refill air for more than 3 months now, no problems even with larger bumps. OK - the rebound adjustment is not very reponsive. It´s only the last view clicks that really have an impact on damping behaviour...

Date Reviewed: May 3, 2006

Strengths:    The motion control is great when the shock actually works

Weaknesses:    Reliability

Bottom Line:   
Bought the bike brand new and on the 3rd ride what feels like the preload mechanism broke causing the shock to travel through 15% of its stroke with no force and then the remaining travel was normal. Tough to ride with it banging up and down like that. Took it back to the shop and they took care of getting a replacement, now after about 30 rides, the same thing again. My next bike will not have a rock shox in the back. I would stay away from this shock unless RS make some serious improvements to the reliability.

Weaknesses:    Had the bike and shock for only two days and the rear shock wasn't holding air preasure.

Bottom Line:   
Rock Shox has some serious quality control issues. Filled the shock to 120 PSI and six hours later..completly deflated. Imagine what would happen on the trail. Shop sent the shock in for a new one. Hopefully I have better luck with the new shock.

Strengths:    Lockout

Weaknesses:    Cant hold air. Pressure drops after 15 min or less of riding.

Bottom Line:   
My experience has been bad with this shock. To be honest, I want something I know will work when riding. Dont get me wrong, Im probably 1 in a million to get this issue, but first impression was a bad one.

When locked out, it still has a little bobbing. The shock would have been perfect for my riding if it worked...unfortunately, it has been nothing but a waste of time and problems.
